The Duecanali 4804 DSP+D from Powersoft is a high-power, four-channel installation amplifier engineered for demanding commercial and professional audio systems. Housed in a compact 1RU chassis and weighing just 7 kg, it features Powersoft’s universal switch-mode power supply with Power Factor Correction, tolerant up to 400VAC, along with a patented ripple-cancellation output filter and low inrush limiting for simplified integration. Advanced thermal management includes temperature-controlled variable-speed fans, front-to-back airflow, and LCD-based temperature forecasting for reliable long-term operation.

The amplifier incorporates comprehensive protection systems, including AC, clip, DC, VHF, short-circuit, long-term RMS limiting, and thermal safeguards up to 80°C. It supports both low-impedance and 70V/100V high-impedance distributed systems, with selectable 35Hz/70Hz high-pass filters, mixed Lo-Z/Hi-Z configurations, and bridged operation per channel pair. Powered by a TI C6000 DSP platform with 24-bit/48kHz converters, it offers advanced equalization (IIR and FIR), up to 100 ms delay, Active DampingControl™, and precise Peak, RMS voltage, RMS current, and TruePower™ limiters. Remote control and monitoring are available via ArmoníaPlus software and a dedicated WebApp, while onboard hardware controls allow flexible adjustment of gain, attenuation, and output modes, making it ideal for large-scale distributed audio installations.
